|2x - 1| = | - x - 2|

Thus ;


2x - 1 = - x - 2

Add both sides x


2x + x - 1 = - x + x - 2


3x - 1 = - 2

Add both sides 1


3x - 1 + 1 = - 2 + 1


3x = - 1

Divide both sides by 3


(3x)/(3) = ( - 1)/(3) \\


x = - (1)/(3) \\

Or


2x - 1 = - ( - x - 2)


2x - 1 = x + 2

Subtract both sides x


2x - x - 1 = x - x + 2


x - 1 = 2

Add both sides 1


x - 1 + 1 = 2 + 1


x = 3

There u go ...
